Description
Technical field
The present invention relates to field of cable technology, and in particular to a kind of cable connector.
Background technology
After cable laying is good, in order to become a continuous circuit, each section of line must be connected as an entirety, these
Tie point is known as cable connector.Cable connector is for locking and fixing inlet-outlet line, play a part of water proof and dust proof against shock.
Because most of cables carry screen layer, therefore in the design process of cable connector, electromagnetic shielding is seldom considered
Problem.But during actual use, it has been found that cable is during cable connector is inserted, what cable was carried
Screen layer is easily broken, so as to lose the effect of electromagnetic shielding, and, the built-in screening arrangement of traditional cable joint can not be front and rear
It is mobile, cause installation to be wasted time and energy.
The content of the invention
Present invention aim at a kind of anti-electric magnetoelectricity cable joint is to provide, to solve above-mentioned at least one technical problem.
To achieve these goals, technical scheme is as follows：
A kind of anti-electric magnetoelectricity cable joint, including one be used to locking and fixing the joint of inlet-outlet line, the joint is provided with a use
In the threading chamber of threading, it is characterised in that be provided with groove annular in shape, the center of the groove on the madial wall in the threading chamber
The central axes in axis and the threading chamber, the notch of the groove towards the threading chamber central axis, it is and described
Width of the width of notch less than the bottom land of the groove；
At least eight are provided with the groove in straight bar-shaped straight-bar, the straight-bar is stuck in the groove,
The top of the straight-bar connects the upper end of the knee in bending that an electromagnetic shielding material is made, the knee
Bottom connect the bottom of adjacent next straight-bar, the top of adjacent next straight-bar connects adjacent next knee
Upper end, be sequentially connected down successively；
The minimum range that each knee is convex to the central axis to the threading chamber is not less than 0.1cm.
The anti-electric magnetoelectricity cable joint of this patent when in use, wear by the center of the knee that cable conductor is made up of electromagnetic shielding material
Cross, therefore cable conductor can be electromagnetically shielded using knee.In addition, the structure of knee, straight-bar, it is allowed to which knee is with straight-bar
Central axis be pivot, rotated, in this manner it is ensured that cable conductor is in joint during double swerve, cable core begins
The center of the structure for being surrounded in multiple knees eventually, realizes 360 degree of shieldings of rotation cable core, installs also easier.
Used as a kind of preferred scheme, the knee is in the knee of arcuation, the minimum between two ends of the knee
